Detailsinfo

A vulnerability, which was classified as problematic, was found in UniteCMS Unlimited Elements for Elementor Plugin up to 2.0.17. This affects some unknown processing of the component AJAX Handler. The manipulation of the argument formData[id] with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. The summary by CVE is:

The Unlimited Elements For Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'formData[id]' Parameter in all versions up to, and including, 2.0.17 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The front-end AJAX handler is registered on the public 'wp' action with no nonce, capability, or referer check, and the raw attacker-controlled id value is interpolated verbatim into an exception message that is echoed back without escaping; when the response is served as text/html rather than application/json, the browser parses the injected markup.
